Porous multicomponent Mn–Sn–Co oxide microspheres (MnSnO3–MC400 and MnSnO3–MC500) have been fabricated using CoSn­(OH)6 nanocubes as templates via controlling pyrolysis of a CoSn­(OH)6/Mn0.5Co0.5CO3 precursor at different temperatures in N2. During the pyrolysis process of CoSn­(OH)6/Mn0.5Co0.5CO3 from 400 to 500 °C, the part of (Co,Mn)­(Co,Mn)2O4 converts into MnCo2O4 accompanied with structural transformation. The MnSnO3–MC400 and MnSnO3–MC500 microspheres as secondary nanomaterials consist of MnSnO3, MnCo2O4, and (Co,Mn)­(Co,Mn)2O4. Benefiting from the advantages of multicomponent synergy and porous secondary nanomaterials, the MnSnO3–MC400 and MnSnO3–MC500 microspheres as anodes exhibit the specific capacities of 1030 and 750 mA h g–1 until 1000 cycles at 1 A g–1 without an obvious capacity decay, respectively.
